I had a REAL hard time getting the transfer slots, cruise AFR to lean out, I should have asked you for help its all good now.
I'll say this, I do NOT shoot for lean cruise afr's cos we are not efi we have carbs and WET manifolds so richer mixture work/run way better for me and many others I build for. Now I don't mean cruising in the 11's or low 12's but cams w/duration and overlap need to be richer and if I want mileage, I cruise my Ranger..........
I understand all that, BUT my Charger is the only car I have to drive, so my AFR is on the edge of lean.
